Description

TECHNICAL FIELD

[0001] The application relates to the technical field of construction safety protection, in particular to a safety protection net for construction. BACKGROUND

[0002] In construction, the safety protection structure of workers is very important, especially when working at a high altitude. A safety net is an essential protective product when working at a high altitude. When working at a high altitude, workers at a construction site often pull up a safety net under the work to avoid human body falling from a high altitude. The existing safety protection net is complicated to install, inconvenient to install, inconvenient for users to use, has a low worker usage rate, has a small safety protection effect on workers, and has a net structure of elastic nylon ropes to increase the buffering effect on heavy objects to play a protection role. However, only the nylon rope is easy to rebound the heavy object due to the elasticity of the safety net itself, so that the heavy object has the risk of secondary falling.

[0003] The document with the prior art announcement number CN220058974U provides a safety protection structure for construction. The device is hinged on a support for construction through a connecting piece to increase the buffering effect of the protection net on heavy objects. The connecting piece mainly reduces the elastic effect of the protection net itself when falling by the combined action of the first and second plug blocks and the first spring, first, second and third air holes in the connecting piece, so as to avoid the secondary falling of the heavy object after the rebound caused by the reaction force of the protection net.

[0004] The prior art scheme in the above has the beneficial effects of the existing technology, but still has the following defects: the device cannot be disassembled when in use, so that the overall carrying occupies a large space, and the single-layer nylon net has poor protection effect.

[0005] In view of this, we propose a safety protection net for construction. CONTENT OF THE UTILITY MODEL
